855102 divided by 9 
Let's see how many times 9 fits into 855102.

Going ahead to step 1:
8 divided by 9 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 9

Step 2:
9 can be fit into 85 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 81 from 85 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 9

On to step 3:
When dividing 45 by 9, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 95.0
Deduct 45 from 45 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 9

Moving on to step 4:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 950.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 9

Advancing to step 5:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 9501.0
If we take 9 away from 10, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 9

On to step 6:
9 can be fit into 12 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 95011.0
If we subtract 9 from 12, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
9 goes into 30 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 95011.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 95011.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 95011.33 with a remainder of 0.003.
